Anyone can dry. Curing requires control.
Most drying and curing systems focus on how fast moisture is removed. Cannatrol controls how water behaves inside the flower.
Longevity begins at post-harvest.
The Cannabis Research Coalition (CRC) conducted a Longevity Study to better understand on a chemical level what occurs during the drying and curing process. The findings from the data reinforce a simple reality: long-term quality is shaped by post-harvest conditions. Vaportrol® Technology is Cannatrol’s patented approach to managing vapor pressure so moisture migrates evenly during drying, then stabilizes through cure and storage. Drying too quickly can lock water into plant fibers and shut the curing process down too early. Cannatrol systems are designed to support predictable, repeatable storage behavior over time by aligning the process to water activity targets – rather than reacting to room humidity.
Why water activity is an industry standard for stability
Water activity (aw) is widely used across food, pharmaceutical, and packaged goods industries to evaluate stability over time because it reflects how moisture behaves within a product, not just in the surrounding air. Relative humidity can describe a room, but aw indicates whether a product is likely to remain stable during holding and storage. The CRC's longevity study reinforces why this matters in cannabis post-harvest: controlling the product’s moisture state supports more consistent long-term outcomes. Cannatrol applies this stability-first measurement approach by pairing vapor pressure control with aw-focused targets through dry - cure - store.
Commercial longevity needs repeatability.
The longevity study highlights what commercial operators already experience: inconsistency during drying and holding shows up later. Vaportrol® Technology manages vapor pressure to guide moisture migration predictably, then supports stable storage conditions by targeting water activity. The result is a more standardized post-harvest process designed to reduce variability across batches, rooms, and facilities, helping quality hold up week after week.
- Standardize drying and holding to reduce batch variability
- Align post-harvest workflows to water activity targets
- Support consistent storage conditions across rooms and facilities
- Build repeatable, defensible post-harvest SOPs
Home longevity without the daily guesswork.
Most home methods rely on chasing humidity and hoping the jar cures itself. The longevity study reinforces why that’s risky: instability early can show up later. Vaportrol® Technology automates the post-harvest environment, guiding moisture out evenly, then maintaining stable conditions through cure and storage, so results are more consistent over time with far less hands-on intervention.
- Consistent dry, cure and storage conditions
- Less trial-and-error chasing humidity
- More predictable long-term storage behavior
- Confidence without constant monitoring
How it works
A longevity-focused workflow: move moisture predictably, then lock in stability.
Sugars Don’t Rush. Neither Should Curing.
As cannabis dries, it naturally releases sugars that influence its aroma, color, and how the flower ages. If drying happens too quickly, this process is cut short, which can make the flower harsh and reduce its long-term quality. Vaportrol controls water activity, allowing those changes to happen gradually. Instead of rushing moisture out of the flower, the system manages how water behaves inside it, turning accelerated drying into true curing.
The process is similar to making maple syrup - which as a Vermont-based company we know very well. Sap isn’t rushed to become sweet by turning up the heat. Instead, it is concentrated slowly so the sugars develop without burning or ruining the final product. The same idea applies to curing cannabis. When moisture moves and balances at the right pace, sugars change naturally instead of getting trapped or lost. Taking your time, not rushing, is what keeps quality high in the long run.
Why not humidity?
Humidity describes the air. Longevity depends on the product.
- Reacts slowly to internal moisture changes
- Can appear “in range” while the product is still changing
- Often requires manual adjustment and intervention
- Direct indicator of product stability
- Predictable across drying, curing, and storage
- Used to evaluate longevity in regulated industries
